VENTILATING DEVICE.

Specification of Letters Patent.

Patented Jan. 17, 1911.

Application filed .Tune 9, 1909. Serial No. 501,157.

To all whom it may concern:

Be it known that I, JAMES ALEXANDER GLASS, of the town of Durham, in the county of Grey, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Ventilating Devices, of which the following is the specification.

My invention relates to improvements in ventilating devices for interiors of buildings, cars and the like, and the object of the invention is to devise a simple and eective and inexpensive device, whereby not only will fresh air be supplied to a room or interior, but at the same time means provided whereby all foul air will be eliminated.

My invention consists of a casing or the like designed to be placed underneath the window or opposite the opening in the wall and made in two parts, the upper part of which has an orifice in the outside wall thereof and a series of horizontally disposed deflecting plates projecting inwardly from the front wall past each other, so as to form a circuitous passage-way terminating at the top of the casing for the admission of the pure air-and the lower portion being formed with end openings, and a central opening, a substantially vertically disposed detlecting plate lying parallel to the central opening and vertically disposed inclined plates extending from the back and converging centrally toward the aforesaid plate and leaving an opening opposite such plate, and vertical passage-ways communicating with the space to the inside of the inclined deflecting plates, the parts being otherwise constructed and arranged in detail as hereinafter more particularly explained.

Figure 1, is a vertical section showing a window frame and casing with my ventilating device applied thereto. Fig. 2, is an outside view of the lower portion of the window showing the location of the device. Fig. 3, is a vertical section' through the line -.c Fig. 1. Fig. t, is a horizontal section through the line Q/-g/ Fig. 1. Fig. 5, is a perspective detail of the Ventilating device complete. Fig. G, is a sectional view showing a modified construction of my device made integral with the window sash. Fig. 7, is a sectional view showing a further modification showing it also integral with the window sash.

In the drawings like letters of reference indicate corresponding parts in each figure.

A is the window frame, B the upper sash and C the lower sash. In this description I shall describe my invention as applied to the window, but it will, of course, be understood that I may with equal facility apply it to any opening in the wall or place it in the wall itself, or form it in the slot itself. In the present illustration, however, I have shown my device underneath the bottom of the lower sash, such sash being raised, and the front portion of the casing of the device extending underneath the same leaving an orifice beneath the bottom of the sash, and the top of the lowermost portion of the casing.

The casing comprises side walls D of steplike form having the upper projection Dl surmounted by a capping board or plate D2. The intermediate portion D3 surmounted by a capping board D4, leaving a space near the wall D5 and the lower front projecting portion DG having a capping board D7 extending between the same and beneath the level of the upper front wall D8 leaving an orilice thereunder. DD is the front board of the lower portion or part of the casing, such front board D9 being secured to the end of the board D?.

2 and 3 are boards or plates extending rearwardly from the front D8. The three boards or plates D4 2 and 3 are preferably equi-distant apart and have interposed between them the deflecting plates 4; and 5, which are equi-distantly disposed and form a circuitous passage-way 6 terminating at the bottom in the opening 7 beneath the sash and the top S. The pure fresh air passes through the opening 7 and through the circuitous passage-way G and out through the opening 8 into the interior of the room or compartment, and the deflecting plates or boards D* Q and 3 and 4 and 5 serve to prevent, I iind in practice, any draft from passing through the opening 8. In fact pure air is introduced into the interior without any appreciable current being noticed.

To eliminate the foul air I provide end orifices 9, which are located at the end of the wall D, the orifice 10 in the bottom 11, a deflecting plate 12, obliquely arranged deflecting plates 13 leaving an opening 14 and an upwardly extending vertical passage-way 15 and a downwardly extending passage-way 16 communicating with the chamber 17 formed beyond the deflecting plate 13. The foul air passes through the vertical passageways 15 and 16, the lower strata of air beias4 ilo

ing taken by the passage-way 16. The air passes up in front of the bacl walls 17 and through the opening 14 and both ends of the detlecting plate 13 down through the opening 10 and out through the end openings 9 in the ends of the wall D9 and between it and the frame A. On account of the peculiar disposition of the projecting plates 12 and 13 and openings 10 and 9 no in-rush of air will take place but the current of foul air will, I find in practice, pass outwardly and thereby remove all impure air from the room. The pure air is introduced in the upper portion of the casing as hereinbefore described and it will thus be seen that there will be a continual circulation of the pure air into the room through the upper portion of the casing and foul air out from the room through the lower portion of the casing and this too without any draft, which is one of the objects, which I specially desire to attain.

In Fig. 6, I show a modified form of my construction in which F is the lower sash of the window with an opening F formed in the lower rail thereof provided with a gauze screen F2. F 3 are the sides of the ventilator which are formed integral with the window sash. F t is a board or plate extending outwardly from the window sash above the opening F and in proximity with the back board F5 of the ventilator. F 1 is a top board extending from the back board in proximity with the window. By means of the boards F5 and F G a circuitous passage is formed from the opening F to the opening F7 leading into the room. By this construction the ventilator is formed integral with the window and is of course raised and lowered therewith.

In Fig'. 7, I show a further modification in which the Ventilator is formed integral with the window as described in relation to Fig. 6 and is formed with side boards FS, bottom board F9 back board F10, top board F11 and with an intermediate board F12 extending from the window sash above the opening F11 formed therein. Bars F1t and F11 depend from the board F12 and a bar F1G extends upwardly from the bottom board Fo of the ventilator into a position intermediate of the bars F11 and F15 thereby forming a circuitous passage F13 leading from the outside atmosphere to the opening F1T leading into the room.

What I claim as my invention is:

1. A Ventilating device for interiors comprising end walls, a top wall, a front wall,

a bottom wall and a back wall, the front wall extending below the bottom walland having end openings and the bottom wall having an opening centrally disposed immediately behind the front wall, a detlecting plate located adjacent to the opening and extending toward each end wall and leaving openings, obliquely disposed vertical walls extending from the back corners and leaving an opening in the center, and passage-ways extending inwardly from the space behind the obliquely set plates as and for the purpose specified.

2. A Ventilating device for interiors comprising two portions, a fresh air inlet portion comprising front, back and top and bottom walls, the front wall having an opening at the bottom thereof and the top wall having an opening at the top thereof diametrically opposite the opening in the front wall, and deflecting plates extending partially from the front wall inwardly and partially fioin the back wall outwardly and interposed between the aforesaid deflecting plates and forming a circuitous passage-way from the bottoni opening to the top opening', and a foul air outlet located beneath and connected to the fresh air outlet portions and comprising end walls, a top wall, a front wall, a bottom wall and a back wall, the front wall extending below the bottoni wall and having end openings and the bottoni wall having end openings and the bottom wall having an opening centrally disposed immediately behind the front wall, a deflecting plate located adjacent to the opening and extending toward each end wall and leaving openings, obliquely disposed vertical walls extending froin the back corners and leaving an opening in the cent-er, and passage-ways extending inwardly from the space behind the obliquely set plates as and for the purpose specified.

3. In a Ventilating device for interiors, a casing having end walls, a top wall, a front wall and a bottom wall, the front wall extending below the bottom wall, a detlecting plate located behind the front wall and having openings at the ends thereof between it and the side walls, and an obliquely disposed wall extending from the back corners forwardly and leaving an opening in the center as and for the purpose specified.
